Multiple choice zoology excretion and osmoregulation micturition urine and urine formation urine formation

What is not a correct fact about the micturition?

  1. 1-2 litres production/day
  2. On standing urine gives pungant odour because it converts to ${ H } _{ 2 }S$ by bacteria.

  3. Normal pH of urine is 6.0

  4. Uric acid forms 0.3% of a normal urine sample

A Correct answer
Explanation

The normal range for 24-hour urine volume is 800 to 2,000 milliliters per day (with a normal fluid intake of about 2 liters per day). Micturition or urination is the process of expelling urine from the bladder. This act is also known as voiding of the bladder. The excretory system in humans includes a pair of kidneys, two ureters, a urinary bladder, and a urethra. So the correct option is '1-2 liters production /day'.

Multiple choice zoology excretion and osmoregulation micturition urine and urine formation urine formation

Choose the correct answers from the following given.
Waste products of adenine and guanine metabolism are excreted by man as

  1. urea

  2. uric acid

  3. ammonia

  4. proteins
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The purines metabolism occur by the action of the enzymes released by the liver and intestine which help in the formation of xanthine which finally converts into uric acid as the end product.

Hence the correct answer is B.

Multiple choice zoology excretion and osmoregulation micturition urine and urine formation urine formation

Micturition is

  1. Removal of urea from blood

  2. Removal of uric acid

  3. Passing out urine

  4. Removal of faecal matter

C Correct answer
Explanation

Urination is the release of urine from the urinary bladder through the urethra to outside of the body. It is also known medically as micturition. Micturition occurs when the bladder neck and the external urinary sphincter relax and the bladder contracts, allowing for the unobstructed expulsion of urine.

Removal of parathyroids in human beings result in

  1. Tetany

  2. Simmond's disease

  3. Myxoedema

  4. Addison's disease
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Parathormone of parathyroid gland increases the blood calcium level. Removal of parathyroid gland decreases the blood calcium level due to its increased excretion in urine. It causes increased excitability of muscles and their sustained contraction referred to as parathyroid tetany. Myxedema is caused by hypothyroidism in adults while Addison’s disease is caused by the presence of ineffective ACTH. Simmond's disease is caused by the destruction of the anterior pituitary lobe. Thus, the correct answer is A.

The over-stretching of tendons and ligaments is called as

  1. Tonus

  2. Tetany

  3. Sprain

  4. Fatigue
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A sprain is an injury to the ligaments around a joint. Ligaments are strong, flexible fibers that hold bones together. When a ligament is stretched too far or tears, the joint will become painful and stress.
Tonus is the slight, continuous contraction of a muscle.
Tetany consists of the involuntary contraction of muscles.
Fatigue is the general overall feeling of tiredness and lack of energy.
So, the correct answer is option C.

Multiple choice zoology locomotion and movement disorders of musculoskeletal system disorders of muscle and skeleton joints and movements

Which of  the following pair is incorrect in relation to diseases and related symptoms-

  1. Rheumatoid arthritis-accumulation of pannus granules

  2. Rickets-Incomplete and insufficient deposition of calcium and phosphate into bones

  3. Gouty Arthritis- Deposition of urea into joints

  4. Osteoporosis- Deficiency of vitamin D

Multiple choice zoology locomotion and movement disorders of musculoskeletal system disorders of muscle and skeleton joints and movements

Which of the following are skeletal disorders? 

  1. Osteoporosis

  2. Arthritis

  3. Diabetes

  4. Both (B) and (A)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Arthritis is a disorder of the joints. It involves inflammation of one or more joints. When affected by arthritis, the joint or joints affected may be painful to move, may move in unusual directions or may be immobile completely. Osteoporosis is a disease of bone where there is reduced bone mineral density, increasing the likelihood of fractures. 

So, the correct answer is 'Both (B) and (A)'.
